To all whom it may concern:

'Be. it known that I, THOMAS W. SM TH, citizen of the United States,residing at Scranton, in the county of Lackawanna and State ofPennsylvania, have invented new and useful Improvements in Lubricators,of

expense for repairs and renewals, by pro-.

viding a lubricator that is calculated through the medium of reducers tobe nicely fitted to piston rods of various diameters.

Another object of the invention is the provision of a piston-rodlubricator embodying improved means for taking lubricant from the hollowbody andv applying the same to the piston rod.

Another object is the provision of a lubricator' embodying body sectionsso constructed and relatively arranged that they are interlocked or heldtogether of themselves. Other advantageous features of the inventionwill be fully understood from the following description and claims whenthe same are read in connection with the drawings, accompanying. andforming part of this specification, in which:

Figure 1 is a front elevation of the lubricator constituting thepreferred embodiment of my invention. Fig. 2 is a vertical-section takenthrough the hollow portion of the body and showing the reducers and thelubricant-applying means in said hollow portion. Fig. 3 is a horizontalsection taken on the line 3+3 of Fig. 1, looking downwardly. Fig. 41 isa rear elevation showing the dove-tail joint between the two sectionsof. the body. Fig. 5 comprises separated views of the two reducersembodied; in the device; theuppernreducer being shown in side elevation,and the lower reducer in longitudinal section.

Similar numerals of reference designate corresponding parts in all of:the views of the drawings. v

The lubricator body may be and preferably 'is made of cast-iron or othercheap material. It is preferably, though notn'neciessarily, formed intwosections as shown.

#The upper section comprises. a hollow :por-

tion 1, of dove-tail form. in outline, entirely openat its lower-sideand havinga filling open1ng2 in itstop' wall, .and a flange plate 3 thatforms a continuation of the: back wall of theihollow portion 1, and hasa dove-tail opening 4 in its lower portion to receive and lit. overthedove-tail hollow body portion 5' of the lower section, and also hasapertures .6, the latter for the passage-of screws or bolts throughwhich the lubricator is to beconnected with the usual-*glandat one endof a piston cylinder. Y Y

In addition to the hollow portion 5 .of dove-tail form in outline,theulower zbOdy section comprisesa flange plate 7 that is arranged'in a.plane slightly 'infront of the back wall of the portion and has a.doveta1l-shaped opening 8 in its upper portion designed to fit; snuglyover and receive the.

hollow portion 1 of the upper body portion. By Virtueof the describedrelative arrange- Inanifest that they will .be intenlocked nd heldtogether of themselves, sothattlleade- I vice can be convenientlyplacedand adjust- .ment of the two body S6C1310I1S,'1t will be r sectionisclosed at its bottom, and its upper end is entirely open andlisopposed-tothe,

lower open end of the hollow -portioni1 complementary to the upper bodysection.

The front walls of said portions 5 .andi1restv seats12. .v

The lower hollow portion 5 is provided with an integral semircircularpartition wall 13 somewhat similar to the wall 9; the

said wall 13 having, preferably but 'not' necessarily, acentral-aperture 1 1,- and also having a central seat 15, andapertures.16

located near its ends. At the endslof the wall 13 the lowerhollowportion 5.;is5providedwith seats 17. 1

said wall 9- said portion 1. is provided with 1 The reducers 18 and 19of the lubricator are preferably made of comparatively soft materialsuch as copper or brass, and it will be understood that the scheme of myinvention contemplates the employment of reducers of different sizes tofit the lubricator to piston rods of different diameters also, that itis purposed when one or a pair of reducers is worn or otherwise impairedto replace the reducer or reducers with new ones without loss of thelubricator as a whole.

The reducers 18 and 19 are identical in construction. Each of saidreducers l8 and 19 is of open-work construction a. 6., has spaced sidebars 20, Fig. 5, and each is provided with a central aperturedprojection 21 designed to rest in the central seat of one of thepartition walls 9 or 13, and end projections 22 designed to rest in theend seats 12 or 17 of one of the hollow per.- tions of the bodysections. it will also be observed by reference to Fig. 3, that theopenwork portions 21*, Fig. 5, of the reducers that bear the projections21 and22 are of reduced width, this to afiord flanges 23 that aredesigned to be opposed to the edgesof the front and back walls of thehollow portions 1 and 5.

The hollow portions 1 and 5 are designed to hold lubricant; thelubricant being supplied through the opening 2 which may be providedwith an approved closure (not shown).

Arranged in the hollow portion 1 of the upper body section are wicks 30which are threaded through the aperture 11 and have portions at oppositesides of the partition 9. The lower portions of the said wicks aredesigned to rest against and supply lubricant to a semi-circular packingsection 31, arranged and held in the upper reducer. The said wicks aredesigned to siphon lubricant from the interior of the upper hollowportion 1 to the packing section 31 which, in turn, is adapted to applythe lubricant to the piston rod (not shown).

Against the upper side of the partition wall 13 in the lower hollowportion 5 is arranged a wick 32. lhis wick has a looped portion 33depending through the aperture 1 1, and also has end portions extendingthrough the apertures 16 and depending in the interior of the portion 5.This wick by siphon action supplies lubricant to a semicircular packingsection 34 arranged and held in the lower reducer, and designed tocooperate with the section 31 in applying lubricant to a piston rod. I

The wicks and the packing sections de scribed are readily removable andrenew- V able.

It will be gathered from the foregoing that either of the reducers 18 or20 may be replaced with a new reducer when worn or impaired; also, thatby using thicker reducers in lieu of those illustrated the device may bereadily fitted to a piston rod of small size in cross-section.

' r 1 would also have it understood that when deemed necessary, thelower hollow portion 5 may be provided with a complementaryfillingaperture and closure means therefor. These, however, 1 have deemed itunnecessary to illustrate, inasmuch as they are not essential to thesuccessful operation of my novel lubricator. V 1

Having described my invention, what I claim and desire to secure byLetters-Pat- .ent, is:

. ends and also having semi-circular apertured partition walls and alsohaving central and end seats, semi-circular open-work reducers removablyarranged in the inner ends of the hollow body portions and against thepartition walls and having projections disposed in said seats, wicksextending through the apertures of the partition walls and arranged atthe inner sides of said walls, and semi-circular packing sectionsarranged in the reducers and against said wicks.

3. In a lubricator, the combination of hollow body portions havingopposed inner ends, removable and renewable reducers arranged in saidinner ends of the body portion, packing means arranged in said reducers,and means for transferring lubricant from the interiors of the bodyportions to the packing means.

5L. In a lubricator, the combination of hollow body portions havingopposed inner ends, removable and renewable reducers arranged in saidinner ends of the body portion, semi-circular packing sections removablyarranged in said reducers, and means for transferring lubricant from theinteriors of the hollow body portions to the packing sections.

5. The combination in a lubricator, of a hollow body having inner andouter compartments, reducing means arranged in the inner compartment ofthe body, packing means in the reducing means, and means fortransferring lubricant from the outer comhollow body having inner andouter compartments, reducing means arranged in the inner compartment ofthe body, packing my hand in presence of two subscribing witmeans in thereducing means, and Wicks oarnesses. ried by the reducers and.arrangedin contact with the packing means and also arranged in the outercompartments of the Witnesses: body.
